Application feed January a1; 1992. serial No. 91,959.` (No man.)

To will wiz/om, t may' concern:

' Be it known that I, THoMAs D. THOMAS, a citizen of the UnitedStates, residing at Redoak, in the county ofMon tgomeryand State ot' Iowa, have invented anew and useful Ruler, Book-Holder, and Marker Combined,

of which the following isa specification.

Myobject is to provide a simple device specially adapted for holding a book open atany lIO ` in section, showingthe manner of detachably point desired to prevent the annoyances incident to books accidentally closing when open for use and valso adapted for marking lines on the pages of a book and when not connected with-abook adapted for all the common purposes of a ruler.

' My invention consistsvin the vdevice here# inafter set forth, pointed out in Vmy claim, and illustrated inthe accompanying drawings, in which@ Y Figure 1 is a perspectivelview of the complete device ready'i'or practical use. Fig. 2 is an enlarged view of the end portion, partly connecting the'two distinct parts of the device. Fig. 3 showsthe device connected with a book as required for retaining the book open and marking lines on .the pages.

'The letter A designates a straight rigid bar, preferably in the shape of a ruler, provided vvith perforationsin its ends adapted to admit hooks. An elastic cord, or preferably an elastic tape B,shorter in length than the bar A, has fastening devices o fixed to its ends, preferably. hooks madeof wire, in such,` a manner that bystretching the tape the hooks can be inserted in the perforations in the ends of the ,bar asx-required to'detach ably and securelyconnect the two separable parts A and B.

To apply the device to an open book, detach one end of the elastic tape from the rigid' bar and then place the bar on the under sidev `of the open book and stretch the tape across the open pages of the book and fasten its vfree end again to the bar-by inserting the hook c in the perforation in the end of the bar. To mark lines on the1 pages, move the device up or down relative to any lines that are to be designated by placing the elastic 1 5o tape immediately above or below such line to extend parallel therewith. Having thus described the purpose, con-l struct-ion, and operation of myinvention, its

practical utility Will be readily understood by readers of books, and

What I claim as new, anddesire by Letters Patent, is

` A book-holder comprising a vstraight rigid bar having perforations in its ends and an elastic cord or tape having hooks at its ends as shown and described for the purposes-v stated.
